DataSieve /watch/standard APIPOST /watch/standard · x402 API by DataSieve
A 7-day watch, ONE condition: on-chain on Base (wallet activity, whale token transfers, price crossings, new pools), a heartbeat dead-man switch for your agent (silence fires the alert), a schedule/cron webhook, or a url-change website monitor (CSS-selector/regex scoped). No account: one paid call returns a watch id + secret. Events push to your webhook (HMAC-signed) and a pollable mailbox, each with a signed Ed25519 receipt. Failed calls never billed. 50 triggers; {"renew":"wt_..."} extends.
